DR. BARBARA STURM Night Serum bolsters the skin's essential overnight processes. This lightweight serum contains cotton thistle extract to combat dryness, while senna alata supports protection against UV-induced damage. Purslane, a potent antioxidant, diminishes inflammation and visible signs of aging. Molecularly balanced hyaluronic acid further replenishes moisture levels. The serum leaves skin feeling plumper, calmer, and incomparably radiant upon waking.
